Equipment

Kettle or pot, Mug or teapot, Strainer or tea infuser, Measuring spoon

5Remove the strainer/herbs. Add honey, lemon, or other herbs to taste if desired.

6Drink 1-3 cups daily, or as directed by a qualified herbalist.

Tips

• Covering while steeping is important — it traps beneficial volatile compounds.
• Leaves and flowers generally need 10-15 minutes; roots and bark need a decoction instead.
• Make larger batches and refrigerate for up to 48 hours.

Start with a small amount to check for any sensitivity. Not all herbs are suitable for tea preparation — some require alcohol extraction (tincture) for full potency.

Drink fresh or refrigerate for up to 48 hours. Dried herbs should be stored in airtight containers away from light.

Decoction (Roots, Bark & Seeds)Easy · 25-45 minutes

Equipment

Pot with lid (non-aluminum), Strainer, Measuring spoon, Stove

Instructions

1Place 1 tablespoon of dried root, bark, or seeds per 12 oz of cold water in a pot.
2Bring to a boil, then reduce heat to a low simmer.
3Cover and simmer for 20-40 minutes. Harder roots (like Astragalus) may need up to 45 minutes.
4The liquid should reduce by about one-third.
5Strain through a fine mesh strainer, pressing the herbs to extract all liquid.
6Drink 1-3 cups daily. Can be combined with honey or blended with an infusion.

Tips

• Use a non-aluminum pot — aluminum can react with plant compounds.
• Decoctions are necessary for roots, bark, seeds, and mushrooms — these are too tough for simple steeping.
• You can simmer mushrooms (Reishi, Chaga) for 2+ hours for stronger extraction.

Some roots are very potent — follow specific dosing guidelines for individual herbs. Avoid decocting herbs with volatile oils (peppermint, chamomile) as you will lose the beneficial compounds.

Refrigerate and use within 48-72 hours. Can be gently reheated.
